GRINDING MECHANISM FOR SHARPENING HORSESHOE-CALKS.

SPECIFICATION forming part of Letters Patent No. 793,159, dated June 27, 1905.

Applisation filed December 14,1903. Serial No. 185,019.

who? it W/ 007M367! ing-collars and the nut 16 is agrinding-wheel Be it known that I, GEORGE A. RUssnLL, 19. Fastened on the shaft 15 is a collar 18. a citizen of the United States, residing at I In this construction it will be seen that the \Vorcester, in the county of orcester and frame and its cover 14 form a socket or State of Massachusetts, have invented a new hood which ineloses the greater part of the and useful Grinding Mechanism forSharpenwheel. Fastened onto the end of the shaft ing Horseshoe-Calks, of which the following is a specification.

This invention relates to a grinding mechanism which has been designed for sharpening horseshoe-calks.

The especial object of this invention is to provide a strong, simple, and eflicicnt tool for utilizing power for sharpening the calks of horseshoes without requiring the shoes to be removed from the horses hoof.

To these ends this invention consists of the grinding apparatus as an article of manufacture and of the combinations of parts therein, as hereinafter described,and more particularly pointed out in the claims at the end of this specification.

In the accompanying drawings, Figure 1 is a perspective view showing the manner in which a grinding mechanism constructed according to this invention is used. Fig. 2 is a plan view, partly in section, of a grinding mechanism constructed according to this invention; and Fig. 3 is a transverse sectional view thereof, taken on the line 3 3 of Fig. 2.

By the use of a grinding mechanism constructed according to my invention I have provided simple and eflicient means of applying power to resharpen horseshoe-calks without the removal of the horseshoes from the horses hoofs.

Referring to the drawings for a detail description of an apparatus constructed according to this invention, 10 (.lesignates a cupshapedsegmental frame. Extending from the opposite side of the frame 10 are bosses 11. Fitting into the bosses 11 are wooden handles 12, which are fastened in place by nuts upon the ends of the rods 13. Bolted onto the frame 10 is a cover 1 1, which may be held from sidewise movement by a smalltlangcQ, as shown in Fig. 3. Journaled in concentric bosses extending from the frame 10 and its cover 11 is a shaft or arbor 15, and fastened upon the shaft or arbor 15 by means of clam pwhich power may be applied from any suitable source for turning the wheel.

In the use of a grinding mechanism as thus constructed the user grasps the handles, which extend at right angles to the axis of the grinding-wheel, and the grinding of the horseshoc calks is done upon the sides or flat faces of the wheel. I prefer to do the grinding upon the sides rather than upon the periphery of the wheel, I have found in practice that the wheel can be more steadily held into engagement with its work and there is less liability for the wheel to jump or run off from the calk with which it is being held into engagement.

A grinding mechanism constructed according to this invention may be used with the same facility for sharpening calks of casehardened or tempered horseshoes that it can be used for ordinary horseshoes.

One especial advantage in the use of the construction as herein illustrated is due to the fact that a casing is provided which ineloses the greater part of the grindingw11eel,so that little damage will be done if the tool should be dropped upon the floor on account of the horse kicking or changing positions.

In the use of my grinding mechanism for sharpening horseshoe-calks both faces of the grinding wheel may be used, an upward pressure being exerted to grind the lower side of a horseshoe-calk, while a downward pressure may be exerted to grind the upper side of a horseshoe-calk, and in all conditions of grinding or sharpening horseshoe-calks a particular advantage of my grinding mechanism is due to the two-handed grip for supporting the emery-wheel, so that the same may be held firmly up to its work, so that it will be less liable to chatter or run off from the same.

I am aware that changes may be made in the construction of my apparatus for grinding the calks of horseshoes withoutdeparting or arbor 15 is a flexible shaft or coil 20, to

from the scope of my invention as expressed in the claims. I do not wish, therefore, to be limited to the construction I have herein shown and described; but

What I do claim, and desire to secure by Letters Patent of the United States, is-

1. In a construction of the class described, the combination of a casing of substantially segmental shape, handles connecting with the casing at diametrical points thereon, a shaft journaled in the casing, and an emery-wheel secured on the shaft and mounted in the easing with one side of the wheel projecting from the casing, whereby either face of the wheel may be used for grinding.

2. In a construction of the class described, the combination of a driving-shaft, an emerywheel, and a two-handed grip for applying the emery-wheel comprisinga segmental cupwitnesses.
